[Ur] Ur/Web on Raspbian

[Karen Sargsyan]

I came to the same conclusion, so I'm more after an easy setup for 
making RPi web applications via
C code produced by Ur/Web compiler hosted on a different machine.
I'll share my setup, as soon as I figure out procedure, make script and 
test on several applications.
